BICYCLE-TIRE.

SPECIFICATION forming part of Letters Patent No. 542,683, dated July 16, 1895.

Application filed January 25, 1893. Serial No. 45916 l7- (No model) To aZZ whom it may concern:

Be it-known that 1, JOHN NAsE, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and usefullmprovements in Bicycle-Tires, of which the following, taken in connection with the accompanying drawings, isa full, clear, and exact description.

The object of this invention is to provide to simple, convenient, and effective means for securing the elastic tire of a bicycle to the felly of the Wheel; and to that end theinvention consists essentially in the combination of the felly provided with outwardly-turned 1 5 flanges, the tire provided with circumferential ribs seated against such flanges, and laterallyspreading plates clamping said ribs on the flanges of the felly, as hereinafter more fully described, and specifically set forth in the claims.

In the annexed drawings, Figures 1, 2, and 3 are transverse sectional views of follies with the elastic tire attached thereto by my improved fastening devices. Fig. 4 is a plan view of the exterior of the fastening devices shown in Fig. l, and Fig. 5 is a plan view of .the inner side of the felly provided with said fastening devices.

Similar letters of reference indicate corresponding parts. 7

0 represents the felly of a bicycle-wheel,

, and D denotes the elastic tire, which may be of any suitable and well-known construction. Said tire is provided with the circumferential ribs 0 0 similar to other tires of this class. To fasten this tire to the felly I form the latter with the circumferential outwardly-turned flanges a a, and preferably bend said flanges toward each other, so as to form them concave on their inner sides, as shown.

Upon the exterior of the felly I place two rings 19 h, each of which is formed with a flange b facing one of the flanges a. Between the flanges Ct at and the adjacent flanges b b are inserted the ribs 0 c of the tire, which are clamped therein by cams d, pivoted to the felly and bearing against the inner sides of the flanges b' b, so as to force the two plates 1) b laterally outward from each other, which effect is produced by turning the cams so as to stand transversely in relation to the felly, as shown in Fig. 4 of the drawings. To permit the cams to be turned as aforesaid the stems d of the cams are made to protrude at the inner side ofthe felly and have affixed to them cross-bars or suitable cross-heads 'i by which to turn the stems with the cams at: tached thereto. The cross-bar 2' is arranged on the stem so as tocause said bar to stand crosswise of the felly when the cam dis turned to spread the plates 1) b apart and clamp the tire on the felly, as before described. I also prefer to form the inward-protruding end of the stem square or otherwise angular for the application of a wrench by which to turn the stem when required.

The flanges a a may project either outward and the cam made to lie over the plates 1) b, as shown in Fig. 1 of the drawings, or said flanges may be made to project inward and the cam lie under the plates 1) b, as represented in Figs. 2 and 3 of the drawings.

Vhen arranged as last described, I prefer to form the felly with the circumferential grooves e 6, into which the edges of the flanges b I) enter whenthe t-ire is clamped on the felly, as shown in Fig. 3 of the drawings.

When it becomes necessary to remove the tire from the felly the cams d are to be turned from'the grip of the flanges.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is r 1. The combination of the felly provided with outwardly turned flanges, the tire provided with circumferential ribs seated against said flanges, and laterally spreading plates clamping said ribs on the flanges of the felly as set forth. 7

2. The combination of the felly provided with outwardly turned flanges aaconcavedin the sides facing each other,rings --bb formed with flanges bb", the tire provided wit-h circumferential ribs cc seated between the flanges a and -b, and the cam dforcing the said rings laterally from each other and clamping 116 gforesaid ribs between the flanges as set ort 3. The combination of the telly formed with outwardly turned flanges aa, rings bb formed with flanges bb', the tire provided with circumferential ribs cc-, seated between said flanges, and the cams d pivoted to the telly and having their stems protruding at the inner side of the felly for turning the cams as and for the purpose set forth.

4. The combination of the felly formed with rings bb providedwith the flanges
